摘　　要：为探究滁州市沙河集水库水质变化趋势和影响因素,利用2014-2016年沙河集水库常规水质监测数据,分析了沙河集水库水质等级、部分常规污染物浓度及其季节性变化特征,并对其影响因素进行了解析。结果表明:沙河集水库水质总体处于Ⅱ-Ⅲ类,氮磷含量较高,水体处于中-富营养化水平,高锰酸盐指数、总氮和总磷年均浓度逐年增大,水质下降;COD_(Mn)、TN含量具有季节性变化,夏秋较高,春冬偏低,TN偶有冬季偏高,TP和叶绿素a季节性变化不明显;根据TN/TP比值的年平均值,滁州市沙河集水库基本为磷限制水体。To explore the water quality variations of Shaheji Reservior and their driving factors,water quality grade,some pollution concentrations and seasonal variations of Reservior Shaheji were comprehensively analyzed by using the water quality data of Reservoir Shaheji during2014-2016.The results showed that:the water quality grade of reservoir by and large reached GradeⅡ-Ⅲof surface water quality requirements.Reservior Shaheji was between mesotrophic and eutrophic.The main pollution concentrations of CODMn、TN and TP increased year by year which indicated water quality declined;The concentration of CODMn and TN varied seasonally obviously,high in summer and autumn,low in spring and winter.The concentration of TN was high occasionally in winter.The concentration of TP and Chlorophyll-a(Chl-a)varied seasonally noticeably;According to the average annual ratio of TN/TP,Reservior Shaheji was phosphorous restricted water.
